Methods of Separating Components of

Mixtures1. Evaporation2. Decantation –” to pour off”3. Distillation – Evaporation + condensation

Methods of Separating Components of

Mixtures4. Fractional Distillation - work with

liquids with different boiling points.a. Boiled to vaporizeb. Fractionating columnc. Vapor to condense

Methods of Separating Components of

Mixtures5. Crystallization - the liquid from a

solution has evaporated to a point beyond the solubility limit.

Methods of Separating Components of

Mixtures6. Chromatography – uses the difference

in degree to which substances are absorbed on the surface of an inert (unreactive) substance; for “colored” materials

Methods of Separating Components of

Mixtures7. Centrifugation- to separate insoluble

materials (usually a solid) from a liquid, where normal filtration does not work well; followed by decantation.

½ CW, box groupingsFor each of the following mixtures, cite an

appropriate technique that will aid in separating its components. Explain and justify your answer.

a. Food dye analysisb. Refining of petroleumc. Purification of beer to increase the alcohol contentd. Separating sand, rocks and water mixturee. Transferring jasmine leaves extract into another

containerf. Separating milk from whey (milk plasma)

In preparation for your QUIZ today, students are to develop a concept map starting with the word

MATTER..

The following key concepts are to be included: pure substance, mixture, element, compound, physical and chemical changes, heterogeneous mixture,

homogeneous mixture, solution, suspension, and colloid; separation techniques.

GIVE EXAMPLES for EACH that were NOT discussed in CLASS.

• Definition, Properties and Characteristics of Matter

• States of Matter• Properties of Matter• Changes in Matter • Classification of Matter• Separation Techniques
